Triple J's Hottest 100 countdown will move to Saturday, January 27, in 2018, the radio station confirms.

The public broadcasting station made the decision to move the popular countdown from Australia Day, January 26, after receiving results from their online survey, which revealed 60 per cent of listeners supported the date change.

In 2016, Triple J said it would be reviewing the tradition of holding the countdown on Australia Day, acknowledging the "increasing debate" about January 26 and its meaning for Indigenous Australians.

"The Hottest 100 wasn’t created as an Australia Day celebration," a statement released on Triple J's website read. "It was created to celebrate your favourite songs of the past year.

"It should be an event that everyone can enjoy together – for both the musicians whose songs make it in and for everyone listening in Australia and around the world. This is really important to us."

As well as moving the date, the countdown will extend over two days moving forward, with the radio station counting down the Hottest 100 songs of the year on Saturday, January 27, followed by songs that ranked 200 to 101 (the Hottest 200) on Sunday, January 28.

According to Triple J, more than 64,000 respondents answered an online questionnaire seeking the public's perspective on the issue. A second survey also returned a majority in favour of moving the date.

The results of both surveys were analysed by an independent company, the station said.

"For those that don't want the date to move, we have heard you," Triple J said.

"We've listened closely to how all of you felt about the Hottest 100 and responded with what's the right choice, right now, that reflects the variety of complicated views."
